	<h3>Basic Overlay Stackability (zIndex and shim support)</h3>

<h4>Setting Up The YUI Instance</h4>

<p>As with the <a href="overlay-xy.html">"Basic XY Positioning"</a> example, to create an instance of an Overlay on your page, the only module you need to request is the <code>overlay</code> module. The <code>overlay</code> module will pull in the <code>widget</code>, <code>widget-stack</code>, <code>widget-position</code>, <code>widget-position-align</code>, <code>widget-position-constrain</code> and <code>widget-stdmod</code> extensions it uses.</p>

<div id="syntax-79a0d897db5a4878eeef6dff77f8706c" class="yui-syntax-highlight"><div class="numbers"><pre class="javascript" style="font-family:monospace;"><ol><li class="li1"><div class="de1">YUI<span class="br0">&#40;</span><span class="br0">&#123;</span>...<span class="br0">&#125;</span><span class="br0">&#41;</span>.<span class="kw2">use</span><span class="br0">&#40;</span><span class="st0">&quot;overlay&quot;</span><span class="sy0">,</span> <span class="kw2">function</span><span class="br0">&#40;</span>Y<span class="br0">&#41;</span> <span class="br0">&#123;</span></div></li><li class="li1"><div class="de1">    <span class="co1">// We'll write example code here, where we have a Y.Overlay class available.</span></div></li><li class="li1"><div class="de1"><span class="br0">&#125;</span><span class="br0">&#41;</span><span class="sy0">;</span></div></li></ol></pre></div><div class="nonumbers"><pre class="javascript" style="font-family:monospace;">YUI<span class="br0">&#40;</span><span class="br0">&#123;</span>...<span class="br0">&#125;</span><span class="br0">&#41;</span>.<span class="kw2">use</span><span class="br0">&#40;</span><span class="st0">&quot;overlay&quot;</span><span class="sy0">,</span> <span class="kw2">function</span><span class="br0">&#40;</span>Y<span class="br0">&#41;</span> <span class="br0">&#123;</span>
    <span class="co1">// We'll write example code here, where we have a Y.Overlay class available.</span>
<span class="br0">&#125;</span><span class="br0">&#41;</span><span class="sy0">;</span></pre></div><textarea id="syntax-79a0d897db5a4878eeef6dff77f8706c-plain">YUI({...}).use("overlay", function(Y) {
    // We'll write example code here, where we have a Y.Overlay class available.
});</textarea></div>
<p>Using the <code>overlay</code> module will also pull down the default CSS required for overlay, on top of which we only need to add our required look/feel CSS for the example.</p>

<h4>Instantiating The Overlay</h4>

<p>For this example we'll instantiate Overlays from script, as we did for the <a href="overlay-align.html">"Alignment Support"</a> example. We'll create 6 Overlay instances and give them increasing zIndex and xy attribute values:</p>

<p>We store the Overlay instances in an <code>overlays</code> array, which we'll later use to sort the Overlays by their zIndex values. We also setup a listener for the <code>zIndex</code> attribute change event, which will update the body section of the Overlay to display its new zIndex value.</p>

<h4>Handling MouseDown Using Widget.getByNode</h4>

<p>The <code>Widget</code> class has a static <code>getByNode</code> method which can be used to retrieve Widget instances based on a node reference. The method will return the closest Widget which contains the given node.</p>

<p>
We'll use this method in a click listener bound to the container of the example ("#overlay-stack"). Target nodes of click events bubbled up to this example container, will be passed to the <code>Widget.getByNode</code> method, to see if an Overlay was clicked on.
</p>

<p>If an Overlay was clicked on, we invoke the simple bringToTop method which will set the zIndex of the clicked Overlay to the highest current Overlay zIndex value.</p>

<h4>The <code>bringToTop</code> Implementation</h4>

<p>We use a basic comparator function to sort the array of Overlays we have. The comparator makes sure the array element we're dealing with <a href="../widget/widget-build.html">has a <code>WidgetStack</code> implementation</a> (which Overlays do) and if so, sorts them in descending <code>zIndex</code> attribute value order:</p>

<h4>CSS: Overlay Look/Feel</h4>

<p>As mentioned in the <a href="overlay-xy.html">"Basic XY Positioning"</a> example, the overlay.css Sam Skin file (build/overlay/assets/skins/sam/overlay.css) provides the default functional CSS for the overlay. Namely the CSS rules to hide the overlay, and position it absolutely. However there's no default out-of-the-box look/feel applied to the Overlay widget.</p>

<p>The example provides it's own look and feel for the Overlay, by defining rules for the content box, header and body sections:</p>
